Residents in the Brooklyn are rushing to file their tax returns before Tuesday's midnight deadline.

For last minute filers, it's important to note only three offices citywide are keeping their doors open until midnight. To avoid penalties, the postal service suggests making sure you have proper postage and the correct IRS address. Also, packages weighing more than 16 ounces must be brought to a post office window.

Finally, don't use an office post meter because it's not viewed by the IRS as proof of timely filing.
